UE Antenna Coherency Signaling for Full Power Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in managing antenna coherence and power transmission efficiency, particularly in multi-input multi-output (MIMO) setups, limiting full power transmission capabilities in coherent user equipment (UE).
Innovation Solution
Implementing a UE with an antenna array and processor to establish communication connections, transmit coherency and power transmission mode capability indicators, and receive instructions to operate in designated modes, enabling full power transmission through coherent and partial coherent modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE operates in coherent mode with antenna array, then signal quality and network performance are improved, but power transmission efficiency is limited and cannot achieve full power utilization
Solution Approach 1:
The system dynamically switches between coherent mode and full power transmission mode based on operational requirements. The UE can operate in coherent mode when signal quality is prioritized, and switch to full power transmission mode when maximum power utilization is needed, making the system adaptable to different transmission scenarios
Solution Approach 2:
The patent introduces capability indicators that allow the network to identify and configure the UE's coherent mode capabilities. By changing the operational parameters through network configuration messages, the system can enable full power transmission for UEs that support coherent mode, thereby resolving the power limitation without sacrificing signal quality
2Power
If the UE transmits capability indicators and receives configuration instructions, then full power transmission is enabled, but device complexity and communication overhead increase
Solution Approach 1:
The UE transmits its coherency capability indicator and power transmission mode capability indicator in advance during the capability exchange phase. This preliminary action allows the network to know the UE's capabilities before configuring transmission parameters, enabling full power transmission without requiring complex real-time negotiations
Solution Approach 2:
The system uses standardized capability indicator formats and configuration message structures that are consistent with existing wireless communication protocols. By copying and extending existing signaling mechanisms rather than creating entirely new protocols, the patent minimizes the increase in device complexity while enabling full power transmission

AI summary
Embodiments are directed to techniques to implement full power transmission in a user equipment (UE). An embodiment of a user equipment (UE) comprises an antenna array comprising a plurality of antenna elements, and a processor to cause the UE to establish a communication connection with a network entity, cause the UE to transmit, to the network entity, a coherency capability indicator and a power transmission mode capability indicator for the UE, cause the UE to receive, from the network entity, instructions to operate in a designated coherency mode and a designated power transmission mode, and configure the UE to operate in the designated coherency mode and the designated power transmission mode.
